More work on the Testcard Generator, yesterday.

-=-=-



I added a new button, "Older", which takes the generated picture and adds some fairly simple noise, blur, and vignette elements to the image.
Really isn't that clever or impressive, but does enough to supply the necessary effect.

What I REALLY wanted to do, was add a little screen curve around the sides, to resemble an older CRT screen. But, having tried a number of ideas, nothing seemed to be working well enough for the effect to work properly.
I'm thinking it might be a good idea to chop the image into hundreds of strips/squares, and rearrange them manually... .. But, boy, that won't be quick in your browser!!

I could, of course, use WebGL and curve it using 3D functions, but that would severely limit the browsers/devices that the page will work on. iOS, as capable as it is, has WebGL disabled by default, and users need to enable it before it'll work. That's not really ideal, and I'd rather not have a giant "Here's how to make my simple webpage work on your powerful modern device" popup!!

No, that's not me. That's not how I work..
Instead, then.. For now.. We'll stick with the vignette, and be happy with it.

.. BE HAPPY!!
